85 307 7A HEADS KEEPS STALLING

1985 Oldsmobile Cutlass • V8 2WD Automatic • 58,652 miles

I have a 85 Oldsmobile Cutlass with a olds 307 5.0. I recently replaced my fuel line going into the carb now the car won't idle without stalling. Any advice? Could it be a vaccuum leak? If so, where? Pictures would be helpful! First time mechanic lol.

Maybe the black fuel lines going from the carb to the purge valve, please pictures will help as well.
